Yes, sometimes. Wi‑Fi devices share radio airtime, so a client connected at a low rate can take longer to send or receive data and leave less time for others—even if its total internet use is small. But one slow device does not automatically slow every network: the effect depends on its traffic, signal, the radio or channel it shares, interference, access-point behavior, and what else is using the network.
Why a low-data device can still use a lot of Wi‑Fi airtime
Internet data volume and Wi‑Fi airtime measure different things. Data volume is how much information a device transfers. Airtime is how long it occupies the shared wireless medium while transferring it. If a client has a weak or low-rate connection, the same transfer can take longer than it would over a faster link. Motorola’s home and small-office Wi‑Fi whitepaper explains that low-rate devices can take longer to complete transactions; NETGEAR notes that legacy clients or clients far from an access point can affect other devices’ performance.
That makes “barely any data” an incomplete clue. A device that sends little data may have little effect if it transmits only occasionally. A device that repeatedly transfers data over a slow link may occupy more airtime. The effect also depends on whether other devices are competing for that same radio and channel; traffic on another band or access point may not share the same bottleneck.

First find out what is actually slow
Before changing router settings or buying equipment, determine whether the problem follows one device, one location, Wi‑Fi generally, or the internet connection as a whole. Try the same online task or speed test on at least two devices near the main router or access point. Results can vary by test service and conditions, so focus first on the pattern rather than a single number.
- Only one device is slow: Check that device’s Wi‑Fi capability, connection status, and software or hardware condition. If it is an older computer, an adapter is worth considering only if its built-in Wi‑Fi is confirmed as the limitation and the adapter is compatible.
- One room or area is slow: Distance, walls or other obstacles, interference, and which mesh or access point serves the device become more likely factors. Check whether it is connected to the nearest eero or access point, if your system reports that information.
- Several Wi‑Fi devices are slow, but wired devices work: Investigate wireless signal, band, channel congestion, client capability, and access-point placement.
- Wired and wireless devices are both slow: Check the modem-to-router link and internet service path rather than assuming Wi‑Fi airtime is the cause.
Google recommends moving a device closer and improving router or point placement; eero advises checking whether a device is connected to the nearest eero. See Google’s slow-internet troubleshooting guidance and eero’s guidance for slow speeds in one area or on one device.

Separate a Wi‑Fi problem from an internet-service problem
If wired as well as wireless devices are slow, compare the connection through the router with the service entering your home. TP-Link recommends, where practical, connecting a computer directly to the modem and comparing results. Follow your modem and ISP’s requirements for this test; some services require particular setup or authentication. If the direct-modem result is similarly slow, the modem or ISP path may be involved. Also inspect the Ethernet cable between the modem and router, since a faulty or unsuitable link can constrain the connection.

Check wireless signal, band, and interference
For problems limited to Wi‑Fi or a particular location, check how far the device is from the access point, what is between them, and which band and access point it uses. A device may support older Wi‑Fi standards or have less capable radio hardware than newer devices. Google notes that 2.4 GHz can be slower than 5 GHz, while also explaining that household devices and neighboring networks can interfere. Which band works better depends on the device, distance, obstacles, and local conditions; do not assume one band is always best.
Router channel and channel-width settings can also affect performance, but there is no universal setting that is best for every home. Congestion, equipment support, and local regulatory conditions matter. Change one setting at a time, if you choose to experiment, and compare results in the same locations. Google’s troubleshooting steps cover placement, device capability, bands, and interference; TP-Link discusses router checks in its slow-internet guide.

Would airtime fairness help?
Airtime fairness is an access-point feature intended to manage how wireless clients share radio time. It may improve aggregate performance in some equipment and situations, particularly when a slow client would otherwise consume a disproportionate share. The feature is implementation-specific: turning it on does not guarantee faster Wi‑Fi for every device, and some implementations may reduce service to older or incompatible clients.
Check the exact feature behavior and compatibility information for your router or access point before enabling it. TP-Link’s Omada explanation describes allocating time slots and includes a vendor test comparing two clients; those results apply to that specific test setup, not as a promise for a typical household. NETGEAR likewise describes airtime fairness as a way to distribute airtime among clients. See TP-Link Omada’s airtime-fairness explanation and NETGEAR’s feature guidance.

Choose a fix based on the bottleneck
| What you observe | What to investigate first | A sensible next step |
|---|---|---|
| One device is slow everywhere | That device’s Wi‑Fi capability and connection | Compare it with another device nearby; consider compatible hardware only if its radio is the measured limitation. |
| Devices are slow only in one part of the home | Signal, obstacles, interference, and serving access point | Test closer to the router or point and check mesh connection or placement. |
| Wi‑Fi is slow but wired service is normal | Radio conditions, band, client capability, or airtime use | Check placement and interference before considering access-point settings such as airtime fairness. |
| Wired and Wi‑Fi service are both slow | Modem, modem-to-router cable, or ISP path | Compare with a direct-modem test where supported and check the Ethernet link. |
A router replacement is not a useful first move without evidence that the access point is the bottleneck. The sources cited here do not establish a universally recommended router model. Likewise, airtime fairness should be considered only after checking the actual symptom and compatibility, not as a blanket fix.
